APPARATUS FOR DYEING WOOL.

SPECIFICATION forming part of Letters Patent No. 415,930, dated November 26, 1889.

Application filed January 25, 1889. serial No. 297,523. No model.)

To all whom it may concern:

Be it known that I, LEONARD WELDoN, of Cohoes, in the county of Albany, in the State of New York, have invented new and useful Improvements in Wool-Dyeing Machines, of

which the following, taken in connection with l the accompanying drawings, is a full, clear,

and exact description.

This invention relates to appliances which, although adapted for dyeing warps and skei nyarn, are more specially designed for dyeing carded or combed wool in the form of slobbingor wool tops.

The object of the invention is to dye the slubbing uniformly and at the same time maintain the fibers thereof in that parallel 7 position in which they are placed by the combing-maohine, and to also prevent said slubbing from matting during the dyeingprocess,

and thus obviate the necessity of recoml'iing the same before Spinning it into yarn, as has been customary in most cases heretofore; and to that-end my invention consistsin the novel construction and combination of the compo nents of the dyeing apparatus, as hereinafter fully described, and specifically setforth in the claims.

In the annexed drawings, Figure 1 is a front view of an apparatus embodying my invention. Fig. 2 is a vertical transverse section of the same with only a portion of the supplemental frames or cylinders connected to the main or dipping frame or cylinder and illustrating the pivotal bearings for the former on the latter. Fig. 3 is an enlarged detached side View and partly longitudinal sectional-view of one of the supplemental cylinders. Fig. 4 is a transverse section of the same, and Fig. 5 is a transverse section of the latter with the slubbing applied thereto and envelopedin a porous or perforated wrapper.

Similar lettcrs'of reference indicate corresponding parts.

A represents the vat containing the dyeliquor; and 1-3 denotes the dipping-frame, which is arranged to move partly in and partly out of said vat, and may be of any suitable form, preferably composed of two heads or end plates secu red at their centers to a shaft (1, which is joyirnalcd horizontally in suitable bearings in the top of opposite ends of the vat and has secured to one of its ends a driving-pulley or gear-wheel b. .The inner side of each of said heads is provided with a series of socketsor bearings c c 0, arranged, preferably, in a circle concentric with the shaft (6 and of any suitable form to permit the attachment and detachment of the supplemental frames or cylinders C (J (l, which are extended lengthwise of the dipping-frame B and have their shafts pivoted at opposite ends in thc aforesaid bearings of the two heads of the dipping-frame.

The supplemental frame (2, I prefer to form of a perforated sheet metal cylindrical body secured at opposite ends to annular heads h h of greater diameters than the aforesaid bodyfso as to form' circumferential flanges thereon. Said heads are provided with openings e e at their centers for the admission of dye-liquor to the interior of the perforated cylinder, said openings being preferably of smaller diameter than the body of the cylinder, so as to form on the ends of 'the latter inward-projecting flanges p, which serve to retain a portion of the dye-liquor in the said cylinder as the same passes out of the vat. One or both ends of eachsupplementalframe or cylinder 0 has cams Z Z projecting from its periphery, andin the path of said camsisa detent a, secured to asnitable support attached to the vat A.

In con nection with the supplemental frames or cylinders O, I employ porous or perforated wrappers d d in the manner and for the-purpose hereinafter explained.

The operation of my improved dyeing apparatus is as follows: The wool combing or slubbing is wrapped evenly around the supplemental frame or cylinder 0 while removed from the dipping-frame A, and after a sulficient quantity is. thus applied a covering (Z, of wire-cloth or other suitable porous or perforated material, is wrapped around the aforesaid wool combing or slubbing and secured After ,the desired number of the rotation it carries the supplemental frames or cylinders C successively into and out of the dye-liquor in the vat. In passing through the said liquor the wrapper (l. enveloping the wool combing or slubbing protects the same, so as to prevent it from becoming matted on thc outside. At the same time a portion of the dye-liquor enters the interior of the supple= mental frame of cylinder ti through the open ends thercof,and inthe passage of said frame or cylinder 0 over the top of the vat the dyeliquor contained in the supplemental frame or cylinder (3 drains through the wool combing or slubbinpon the bottom of said frame or cylinder, while the dye-li uor on the outside of the wool combingor slubhing carried on the upper part of the frame or cylinder C drains to the interior of the latter, and in passing the detent n the sup 'ilemental frame or cylinder t. receives a partial rotation independently of the main cylinder or dipping-frame ii, and thereby causes ditierent portions of the supplemental frame or cylinder to he carried above and beneath the axis thereof. Said change of the position of the peripheries of the supplemental frames in relat ion to the axis thereof, together with the drainings of the dye-liquor in opposite direet-ions thrtmgh the wool combings or slubbing, causes the same to he etl'eetually and uniformly dyed.

\Vhat I claim as new,and desire to secure by Letters Patent, is

1. An apparatus for dyeing sluhhine' or "wool tops, comprising a dye-vat, av dippingframe arranged to move partly in and partly out of said vat, supplen'iental frames in said dipping-frame, adapted to carry wrapped around them the articles to be dyed, and porous wrappers adapted to be folded around said articles carried on the supplemental frames, as set forth.

2. In combination with the dye-Nat and dipping-frame pivoted horizmitally and ar-.. ranged partly in the rat, perforated hollow frames each adapted to carry wrappedaround its exterior the articles to be dyed, having openings in its ends and so arranged that it may be reversed in its bearings independently of the others in the dipping-frame, as set forth.

I An apparatus for dyeing wool tops, consisting of a dye-vat, a dipping-frame pivoted horizontally near or on top of the vat, carryint, perforated hollow cylinders each adapted to carry wrapped around its exterior a layer of tops, and having open ends and supported in the dip 'iing-frame, as and for the purpose set forth. Y

-t. An apparatus for dyeing wool tops, composed of a dye-vat, a rotary dipping-frame arranged partly in said vat, perforated holand each of said cylinders adapted to carry wrapped around it a layer of wool tops, and porous wrappers adapted to be folded around the wool tops carried on the said cylinders, substantially as and for the purpose set forth.

In an apparatus for dyeing slubbing or wool tops, the combination of thevat A, frame B, dippingin said vat, the cylinders C (,carried in the said dipping-frame, and each of said cylinders etrgnposed of a perforated sheet-metal body and of heads 71 71, provided with openings in{their-centers, and porous wrappers applied,h'espectively, to the. slabhing or wool tops wrapped around the cylinders, substantially as described and shown.

(i. In an apparatus for dyeing slubbing or wool tops, the combination of the vat-A, frame 8, dipping iii said vat, the cylinder C, arranged in said dipping-frame and composed of a perforated sheetmetal body, and of. heads I: ll, of greater diameters than the body and provided with openings in the centers of the heads;substantially as described and shown. r I

Tn testi mouy whereof I have hereunto signed my name, in the presence of two witnesses, at tohoes, in the county of Albany, in the State of New York, this 21st day of January, 1989.
